Kate – who presents Good Morning Britain – said she was "shocked" at her reflection because she'd lost so much weight.
She also said she wasn't expecting to see her "really crazy" hair and eyebrows.
Speaking after a shower at the plush Palazzo Versace hotel, Kate revealed that she had lost a stone during her jungle stint.
She said: "I was a bit shocked when I got into the dressing room and looked in the mirror."
I was a bit shocked when I got into the dressing room and looked in the mirror.
Kate added: "I thought, oh, my God! Because you don’t see yourself. There is no mirror in the jungle."
One of the first things Kate did when she left the jungle was take a bath.
She went on to reveal that contestants are weighed before they enter the jungle and when they come out.
She added: "And I’ve lost a stone."
And, it seems, she quite liked her jungle diet.
Said Kate: "I was really eating in there as well, so rice and beans is kind of the way to go."
